Solving Equations

2. One step (subtraction)1)
Subtract 5 from both sides
x+5=20 -5=-5 x=15

3. One step (addition)
addition
Z-25=12 +25=+25 Z=37
Add 25 to both sides

4. One step (division)
Division:
3x=6 3=3 X=2
Divide by 3 on both sides

5. One step (multiplication)
*6 (x/6)=5 *6 X=30
Multiply 6

6. Two step (addition, division)
Addition and division:
3x-2=7 +2=+2 3x=9 3=3 X=3
Add 2 to both sides.
Divide by 3 on both sides.

7. Two step (subtraction, division)
Subtraction and division:
3x+2=14 -2=-2 3x=12 3=3 X=4
Subtract 2 from both sides
Divide by 3 on both sides

8. Two step (addition, multiplication)
Addition and multiplication:
z/2-6=8 +6=+6 *2 z/2=14 *2 Z=28
Add 6 to both sides
Multiply 2 on both sides

9. Two step (addition, multiplication)
Addition and multiplication:
z/4-2=6 +2=+2 *4 z/4=8 *4 Z=32
Add 2 to both sides
Multiply 4 on both sides

10. Multi-step equation (two variables-same sides)
2x+5x=49
7x=49 7
X=7
Combine like terms
Divide by 7 on both sides

11. Multi-step equation (two variables-different sides)
Get your variables on the same sides by subtracting 2x from both sides
Add 5 to both sides
Divide both sides by 3
7x-5=4x+8 -4x -4x 3x=13 3=3 X=4.333

12. Multi-step equations (using distributive property)
Distribute the 2 from the out side of the parenthesis
Subtract 6 from both sides
Divide both sides by 3
3(x+4)=9 3x+12=9 -12=-12 3x=-3 3=3 X=-1
